ABSTRACT:
Multiaxis rotational molding apparatus includes a support portion, a molding portion, a mixing portion and a control portion. The support portion includes an arm member disposed in a generally horizontal orientation and having one end extending from an upstanding supporting section. The molding portion includes a mold supporting assembly pivotally connected to a free end of the arm member and an independently rotatable mold connector section. The mold supporting assembly includes a central passage therethrough from a pivotal connection with the arm member and through the mold connector section. A mold assembly includes at least two separable mold sections forming a substantially enclosed cavity. The mixing portion includes an elongated section extending axially within the central passage through the mold supporting assembly adjacent the mold connector section. The mixing section includes a plurality of deflector sections disposed along the length thereof. A plurality of inlet conduits extends along the arm member and is operatively connected to an inlet end of the mixing section. A hollow probe member extends from an outlet end of the mixing section into the cavity of the mold assembly. The control portion includes actuators rotating the mold connector section and the mold assembly affixed thereto and actuators pivoting the mold supporting assembly and the mold assembly affixed thereto with respect to the arm member, a programmable memory, a coordinator, monitors and circuitry.
